Investigations of carotenoids in some fauna of the Adriatic Sea. III. Leander (Palaemon) serratus and Nephrops norvegicus (Crustacea: Decapoda)

Investigations have been carried out on the carotenoids in Leander (Palaemon) serratus (Pennant) and Nephrops norvegicus (L.) (Crustacea: Decapoda) from the Adriatic Sea. The presence of the carotenoids was determined by means of columnar and thin-layer chromatography. The following carotenoids were found: Leander serratus: β-carotene, echinenone, isocryptoxanthin, cryptoxanthin, canthaxanthin, lutein, isozeaxanthin, zeaxanthin, astaxanthin, and astacene; Nephrops norvegicus: β-carotene, lutein, zeaxanthin, astaxanthin, and astacene.
